Research

Tools of the trade

Hired by Science and Mathematics Education as a content specialist, I continue earth science research. Most of my work has focused on solutions to problems that rely on field observations, careful sampling, and subsequent microscopic research. Some of the most interesting discoveries are the small things such as the usefulness of a microvertebrate population, or the importance of the rapid evolution of planktonic foraminiferans and Radiolaria. Among our most important work, Emile Pessagno and I (as well as John Lewis and Hans Schellekens) contributed to the solutions of terrane ages and plate movements in the Caribbean using radiolarian microfossils. Presently, I am mostly involved in studying cores that include small foraminifers and transported sand and shell that tell stories of huge waves sweeping over barrier islands hundreds to thousands of years ago. The work in the Big Bend also continues.

The present

  1. A third manuscript in a paleoecology series from the Big Bend of Texas. This one details the paleoecology of a field of giant clams in the Boquillas Formation. Work is progressing on their dispersion, orientation, epibiont load, and age at death as well as details of water temperature, bottom currents, dysaerobic conditions, and other factors. Data on the foraminifers in the supporting sediment and the presence of apparent predators is also included.
  2. Paleotempestology of the Gulf of Mexico margin and in the Caribbean. The goal is to trace major storms back in time for a few thousand years based mostly on sedimentology, paleontology, and radiometric dating. Several cores are promising.
  3. Assessment of microplastics in the coastal ecosystem. Work has begun in association with two talented researchers in the chemistry department at UTD.

The first project on microplastics in the bay behind Follets Island revealed a preponderance of rayon fibers. An honors project by Mai Huynh in the Chemistry Department confirmed the composition.

Recent - education

Of particular interest is incorporating research into education. My frst graduate student to work on this sort of project is Hillary Fulgham who is working on the Follets Island cores for the first half of her thesis. The second half will be the creation of a Project Based Learning unit that stems from her research. She expects to publish each part. Hopefully, there will be other graduate students who follow this model.

Research support

Happily, I have private funding for my work in the Big Bend. Among the most welcome benefits is jet travel between Dallas and Lajitas. A one hour and ten-minute flight replaces ten hours of tedious driving. Quite nice lodging as well as field equipment and supplies are also included.

The long commute is so much easier with this aircraft.


The future

I plan to leave UTD in the summer of 2018 to pursue other projects.
